The shootings took place in a driveway outside a home the couple shared near South 5th Street and West Bottsford Avenue.

"I assume if there was a fight I would have heard that. I heard nothing. All we heard was, 'Bam, bam, bam,' and that's when I jumped up," neighbor Anthony Tracy said.

Tracy was home with his dad when he heard what sounded like gunfire coming from the house behind them.

"It's scary because it's close to home," Tracy said.

Police said just before 9 a.m., 39-year-old Annemarie Bautch returned home from dropping her kids off at school when her live-in boyfriend pulled in behind her in the taxicab he drove for hire, walked to her van's window and shot her in the head.

Investigators said 41-year-old Daniel Billings then turned the gun on himself.

"We looked over there immediately because it's just something that came from that way. We could see the windshield wipers, and I said, 'Looks like the windshield is busted out,'" Tracy said.

Mary Ellen Lepak said she ran over to the house when she heard the shots. She said saw spotted Billings on the ground and Bautsch in the minivan.

"He had a gun laying flat on his back with his eyes wide open," Lepak said. "I checked in the window to see if she had a pulse. In the process, I was talking to 911 and getting them the right address. Eventually police came, but I told them, 'It's too late.'"

WISN 12 News has learned Billings was a convicted felon and was prohibited from carrying weapons. He was also on probation for a recent domestic violence incident involving his daughter.

According to a criminal complaint, he repeatedly struck his daughter after accusing her of telling his girlfriend he'd fathered a child with another woman.

Neighbor William Peters said he didn't see this coming.

"Quiet couple, no problems, no yelling, no screaming, none of that stuff ever," neighbor William Peters said.

On Sunday, Bautch updated her Facebook page to add the quote, "Love is all about finding people who are your kind of crazy." The page is full of photos of friends and family, but none of Billings.

A Billings co-worker said the couple was breaking up.

"You always say you don't think it would happen in your neighborhood, and here we go," Peters said.

Neighbors said the couple had three kids, but none in common. Police said they're all OK.

Billings had firearms arrests dating back 20 years. He was ordered to undergo anger management training after his most recent conviction. It's unclear whether that ever happened.

Police continue to investigate the circumstances that prompted the shooting.

WISN 12 News has also learned that the Milwaukee Area Domestic Animal Control Commission was called to the scene to remove three dogs from the home.
